Medical connector with spanning arms

An extension set connector for coupling to a circular hub of an enteral feeding device, the circular hub having a radius, a top surface, a side surface, and an annular recess defined in the side surface, the connector comprising:

• a cap having a top surface, a bottom surface, and a circumferential region defining a bottom plane and a periphery;
• at least two arms, each arm spanning across the bottom plane between radially opposite recessed portions defined with the circumferential region so that each arm is positioned to releasably engage the annular recess;
• a deflection member disposed at each of the recessed portions within the circumferential region and connected directly to both of the arms to deflect the arms, the deflection member being accessible from the top surface;
• the deflection members connected to each other by only the two arms;
• a conduit defining a fluid pathway through the connector, the conduit configured to supply a feeding solution to a lumen of the enteral feeding device,
• wherein the connector is free to rotate completely about the circular hub, and wherein the connector decouples from the circular hub by pressing at least one deflection member radially into its respective recessed portion towards the radially opposite recessed portion in the circumferential region to reversibly deflect at least one arm between the two recessed portions of the circumferential region towards the periphery within the cap in order to disengage from the annular recess.

A feeding extension set, comprising:

• a tube;
• and
• a connector in fluid communication with the tube, the connector configured for rotatably coupling the tube to an enteral feeding device that has a circular hub, the connector including:
• a cap having a top surface, a bottom surface, and a circumferential region with a periphery;
• at least two arms, each arm spanning across the bottom surface between radially opposite recessed portions defined in the circumferential region so it is positioned to releasably engage an annular recess defined in a side surface of the circular hub;
• a deflection member disposed at each of the recessed portions within the circumferential region and connected directly to both of the arms to deflect the arms, the deflection member being accessible from the top surface;
• the deflection members connected to each other by only the two arms;
• a conduit defining a fluid pathway through the connector, the conduit configured to supply a feeding solution to a passageway of the enteral feeding device,
• wherein the connector is coupled to the circular hub by the arms that engage the annular recess such that the connector is free to rotate completely about the circular hub, and wherein the connector decouples from the circular hub by pressing at least one deflection member radially into the recessed portion towards the radially opposite recessed portion in the circumferential region to reversibly deflect the arm relative to the circumferential region in order to disengage from the annular recess.
